# The Somerton Man was a Cold War spy killed by a secret code and poison

**No verdict.** Genealogical DNA analysis has most likely resolved who he was, but how he died, why he was in Adelaide, and what the handwritten code means remain unexplained, and the espionage theory itself is unsupported.

## Summary
An unidentified man found dead on an Adelaide beach in 1948, with his labels cut out, an untraceable poison, and a scrap reading 'Tamám Shud' sewn into his trousers: a mystery that fed decades of Cold War spy speculation until 2022 DNA work pointed to a Melbourne engineer, without explaining how or why he died.

## The claim
That the man found dead on Somerton Beach on 1 December 1948 was a Cold War intelligence operative (a spy or courier) who was poisoned as part of an espionage operation, and that the uncracked code found in his copy of the Rubáiyát of Omar Khayyám is an encrypted message tied to that operation.

## Origin and timeline
- 1948-12-01: A well-dressed man is found dead, seated against the sea wall at Somerton Park beach, Adelaide, with no identification and every clothing label removed or cut away.
- 1949-01: A scrap of paper reading 'Tamám Shud' (the final words of the Rubáiyát of Omar Khayyám, meaning 'ended' or 'finished') is found sewn into a hidden fob pocket in his trousers.
- 1949-06: The coronial inquest opens; a copy of the Rubáiyát matching the torn scrap is handed in, containing an unlisted phone number and five lines of handwritten capital letters resembling a code.
- 1949: The inquest adjourns without identifying the man or determining a cause of death, though the coroner states he would be prepared to find the death was caused by an undetectable poison.
- 2022-07-26: A University of Adelaide team led by Professor Derek Abbott, working with genealogist Colleen Fitzpatrick, announces a DNA-and-genealogy identification: Carl 'Charles' Webb, a Melbourne-born electrical engineer.

## The evidence, claim by claim
- Claim: His identity was erased on purpose: every label was cut out of his clothes.
  Evidence: True, and genuinely strange. But label removal was also common practice among people avoiding creditors, family, or a troubled personal history, not only among intelligence operatives. No dry-cleaning marks or other evidence in the case has ever been tied to an intelligence agency.
- Claim: A hidden pocket held a scrap from a rare, ritually significant text, and the matching book contained an uncracked code.
  Evidence: The paper and book are real and remain in South Australian custody. But cryptographers who examined the code found too few characters to determine whether it is a genuine cipher or a personal shorthand (a list, initials, or a mnemonic), and no cryptologic authority has ever linked it to a foreign intelligence service.
- Claim: A woman he was connected to was evasive about him and appeared to know more than she said.
  Evidence: Jessica Thomson, whose telephone number was written in the book, did decline to identify him and later behaviour suggested she knew something. That is evidence of a personal secret, not a demonstrated one of espionage; no corroborated intelligence record has ever named her, or the Somerton Man, as a foreign agent.

## Why people believe it
- The circumstances were genuinely anomalous (an untraceable death, deliberately removed labels, and a coded message), and anomalies invite the most dramatic available explanation.
- It happened in 1948, at the exact dawn of the Cold War, with Adelaide hosting genuine intelligence-related conferences that year, giving the espionage reading real period plausibility.
- The case resisted resolution for 74 years, and a vacuum that long lets every fragment of suggestive evidence (a code, a torn book, an evasive witness) accumulate into a narrative no single fact can outweigh.

## Open questions
- No toxicology test, in 1948 or since, has identified an actual poison in his body. Professor Cedric Stanton Hicks proposed two candidate cardiac glycosides at the inquest (later revealed as digitalis and ouabain), and a 1994 judicial review by Chief Justice John Harber Phillips concluded 'there seems little doubt it was digitalis.' But government analyst Robert Cowan's original tests found no foreign substance at all, and Derek Abbott and Colleen Fitzpatrick's own theory, that a distressed Carl Webb took his own life, remains an inference from biography, not a confirmed cause of death.
- The five lines of capital letters pressed into the back cover of the recovered Rubáiyát have never been read, by anyone, in any direction. The strongest technical analysis makes a personal shorthand more statistically likely than a formal cipher, but 'more likely' is not 'solved': no reading of the lines, coded or otherwise, has ever been verified or agreed upon by any cryptographer or linguist who has examined them.
- Confirming Carl Webb's name does not explain why he was on Somerton Beach, whether he knew Jessica Thomson before his death, or what, if anything, passed between them. The two have no confirmed direct relationship on paper. Thomson's visible shock at his death mask, her lifelong evasiveness about him, and her son Robin's striking but ultimately coincidental physical resemblance to the dead man leave a residue of mystery around her that nothing has fully explained.
- Whether any of this amounts to espionage looks weaker now than it did in 1948, but the theory is not fully closed either. Webb's confirmed biography, that of an estranged instrument maker with no known government, military, or diplomatic record, gives it no one to attach to. But that biography still doesn't explain why an ordinary tradesman would have had every clothing label deliberately removed, or end up dead of an undetectable poison beside a coded note, so the theory persists less on evidence than on the absence of any competing explanation for those two specific facts.
